When Combe Martin self-builders specify UFH, the screed is what makes the system efficient. We pump Cemfloor Therm directly around your pressure-tested pipework for full encapsulation.
For Combe Martin UFH builds the typical sequence is: insulation board down, pipes clipped and pressure-tested, edge insulation in place, then we pump and level in a single visit.
Most of our Combe Martin jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Combe Martin sits Barnstaple (15 mi), and we work the surrounding villages on the same week's diary.
Who this is for in Combe Martin
Combe Martin is a coastal town, so damp control, salt exposure and tight winter pour windows shape every brief. We work the diary around that — and around the holiday-let turnover that funds half the jobs here.

Underfloor Heating Screed in Combe Martin — how it works
Liquid UFH screed lets you run a thinner build-up than traditional bays — useful when ceiling heights or threshold levels are tight in Combe Martin renovations.
We pour Cemfloor Therm liquid screed over your UFH pipes at 50mm above pipe (typically 65-75mm total over insulation), giving full pipe encapsulation, fast thermal response and a finished surface flat to SR1.

PIR/Phenolic insulation board
70-150mm typical depending on build regs U-value target.
Edge insulation strip
Critical around UFH zones to allow thermal expansion.
Pressure-testing kit
Pipes held at 6 bar through the pour to flag any damage immediately.

Common Combe Martin build questions
When can I switch the underfloor heating on in Combe Martin?+
On Cemfloor Therm we typically start a slow commissioning cycle from day 7, ramping 5°C per day per manufacturer spec. Forcing it earlier risks cracking, so we hold Combe Martin clients to the schedule.
What if a pipe leaks during the pour?+
Pipes are held at 6 bar through the pour. Any pressure drop is flagged immediately and we stop, fix and continue — this is exactly why we keep the manifold under test.
Will the screed crack as the UFH heats up?+
Properly isolated at the edges and at doorway joints, no. We pour with the pipes pressure-tested and follow a controlled commissioning schedule.
What depth of screed over UFH pipes do you recommend?+
Minimum 50mm cover above the highest pipe — usually a 65-75mm total slab over insulation. Thicker if you want more thermal mass.
Does liquid UFH screed improve EPC ratings?+
Indirectly — yes. Faster response and lower running temperatures help heat-pump COP, which feeds into your SAP/EPC. We'll share the manufacturer data your assessor needs.
Why use liquid screed over UFH rather than sand-and-cement?+
Liquid screed flows around the pipes with no voids, giving 20-30% better thermal response and lower running costs than a hand-laid screed. That's why most Combe Martin UFH installers recommend it.
